BELT BUCKLE.

' Application filed July l, 1924:. Serial No. 723,537.

T 0 all 1071 am it vim-y] 007266771) Be it known that I, Anonrn H. 111mm, a

citizen of the United States, residing at At tleboro, in the county of Bristoland State of Massachusetts, have invent-edcertain new and useful lmprovementsin Belt Buckles, of which the following 1s a specification. V

Thls invention relates to that class 01' buckles which are provided witha pivoting clamping member adapted to engage and bindbelts of different. thicknesses again the buckle body: and an object of this invention is to provide a clamping member for the buckle, which is formed of a plurality of plates of sheet material, which areconnected together in such a manner as to provide a plurality of different belt clamping edges.

A further objecto't'this invention is to formflthe clamping member of channel bar which provides two spaced apartclamping; edges, and to mount a filler member in said channel which provides an intermediate clamping edge. i

A still. further object of the invention is to mount a separate pivot pin in the space between the side walls of the channel to pivot thev clamp in the body of the buckle and to also pivot the bail member in the; clamp, these plvotlng axes being n difierent vertical planes.

lVith these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a plan view of the inner side of a buckle. body showing: my improved clamping member as pivoted therein.

And the following is a detailed description of. the present embodiment of" my invention showingfone meansby which these advantageous results may be accom phshed:-

tion to-beused in this style of buckle, that i's the clampingineinber may be made up of a plurality of plates set side by side and secured together. i I

.Toform a clamp of my improved con- V 9 It is found. in. practice that a laminated clamping plate is a very practical construcstruction, I preferably provide'first a chan- 'nel bar 13 which-is U-shape'd in cross section one side wall. 14 being of a greater length than the other side wall 15, eachbe+ ing' provided with a gripping edge to engage and bind a belt against theinner. surface of the body'ofthe buckle. I

In order to provide an; intermediate gripping edge between the side edges, I have provided arpair of. filler plates 16land 17,

the plate 16 beingr substantially the full depth of the channel bar while tl ie 'plate l'l' is less than the, full depth of this bar, the

central'meeting edges of these two plates 16 and 17 providing anintermediate belt-gripping edge 18 sofa height less than the edge '14 of the channel bar and greaterithan that of the edge '15 of this bar.

, portions of the two-part pivot pin 21, also this jplate17'is cut away as at22 leaving r space' for the offset portion 23 of the two-1 part" pivot pin, the ends 2 L of this pin member serving toextend beyond the ends of the" channel bar to enter openings 25 in the bearing' earsll of the buckle body to serve as a pivot bearing forfthe clamping bar. The two part pivot pin constitutes the pivot-pin 7 member. "I p w 7 p [I' have providedabail-.member 26 whichmay be pivotally connected to the clamping bar and to receive which I have slotted as at "27' the back of thechannel bar and also that of the filler plates at 27 and 27 through which slots the shank portion of i the pivot pinsextend.

The bail member 26 is provided with eyes 28 at; its'inner ends, see Figure 9, through whichi'the innerends of this divided pivot pin i 2l 'lex tend and the lower portion of] tliis'ba'illis flattened 'as at'29 so that whenits outer en'd'is raised the portion 29 will en-j gage'g'the edge ;of the slot 27 to form a stop and so "assist in lifting the biting edge j of the clamp out of engagement with the belt 31-;Qals0 whenthe bail 26 is swung downwardly it isiadapted to engage an edge32 of the 's'lot 27 thereby swinging the clamp f w bar-downwardly into engagement with in th: belt. Y 7

made upof a plurality of plates set sideby sidefandthese plates are connected together'bypins 33, and the .pivot pins 21 are formed of separate pieces of stock and are inserted into the clamping member after the plates have been assembled to serve a double purpose, first, to provide a pin pivoted in the ears. 11 on whiclrthe clamp is mountecl,and second to provide a pivot on which openingin the bail ends to receive its crankshaped ends but Where made in fhalves their.

inner ends maybe readily passed through th small ball eye required. 1

In some instances in providing a lamlnated channel bar instead of mounting separate-filler plates between the side walls of thechanne-l bar, these plates may, in some cases, be formed by folding these walls inwardly to provide double walls 37 and 34 if desired, as shown in Figure 10, the 'wall 34 being preferably shorter than wall 37 to provide an opening .35 for the reception of the pivot, pins. In other "instances, where the inner plates are formed separate- 1y, I may, as shown in Figure 11,'forrn. in-

tegral" protuberances 36 on these plates to Y fit in corresponding openings in the adjacent walls of the channelbar inv using through pins 33.
